Onset of Magnetic Order in Strongly-Correlated Systems from First Principles: Application to Transition Metal Oxides

Understanding the interplay between electron charge and spin degrees of freedom is crucial in materials of possible technological interest. This requires a full quantum description of the electron spin. For low temperatures, a magnetic material has an electronic structure which has a fixed spin polarization, e.g. a uniform spin polarization for a ferromagnet or fixed sublattice spin polarizatio...

Magnetic Order in Transition Metal Oxides with Orbital Degrees of Freedom

We investigate the frustrated magnetic interactions in cubic transition metal oxides with orbital degeneracy. The eg orbitals order easier and their ordering explains the A-type antiferromagnetic phase in KCuF3 and LaMnO3. In t2g systems the magnetic order changes at a transition from an orbital liquid to orbital ordered states. The fluctuations of t2g orbitals play a prominent role in LaVO3 an...

Electroplating lithium transition metal oxides

Materials synthesis often provides opportunities for innovation. We demonstrate a general low-temperature (260°C) molten salt electrodeposition approach to directly electroplate the important lithium-ion (Li-ion) battery cathode materials LiCoO2, LiMn2O4, and Al-doped LiCoO2. The crystallinities and electrochemical capacities of the electroplated oxides are comparable to those of the powders sy...

Spectral functions in doped transition metal oxides

We present experimental photoemission and inverse photoemission spectra of SrTiO3−δ representing electron doped d 0 systems. Photoemission spectra in presence of electron doping exhibit prominent features arising from electron correlation effects, while the inverse photoemssion spectra are dominated by spectral features explainable within single-particle approaches. We show that such a spectral...
